This new qubit could be 100 times less error-prone in superfluid quantum computer breakthrough
Researchers at the University of Surrey have proposed a new qubit design using superfluid helium-3 to reduce error rates in quantum computing. This 'SHOQ' device is theorized to be 100 times less error-prone than current superconducting qubits by avoiding electromagnetic noise.
Why it matters
Improving qubit stability is a critical hurdle for scaling quantum computers to practical, real-world applications.
Researchers at the University of Surrey have proposed a new kind of qubit that could help address one of the biggest obstacles in quantum computing: keeping error rates low as systems become larger.
The concept uses superfluid helium, a form of helium with unusual quantum properties, to create a qubit that may be less sensitive to some of the disturbances that affect today's leading quantum computers.
Why Quantum Computers Struggle With Errors
Quantum computers rely on qubits to store and process information in ways that conventional computers cannot. Many current systems use superconducting circuits, but these are highly sensitive to electromagnetic noise and stray electrical charges - similar to the static electricity that can make hair cling to a balloon.
